With Micrel KSZ8061 PHY, the link may occasionally not come up after
Ethernet cable connect. The vendor's (Microchip, former Micrel) errata
sheet 80000688A.pdf descripes the problem and possible workarounds in
detail, see below.
The batch implements workaround 1, which permanently fixes the issue.
DESCRIPTION
Link-up may not occur properly when the Ethernet cable is initially
connected. This issue occurs more commonly when the cable is connected
slowly, but it may occur any time a cable is connected. This issue occurs
in the auto-negotiation circuit, and will not occur if auto-negotiation
is disabled (which requires that the two link partners be set to the
same speed and duplex).
END USER IMPLICATIONS
When this issue occurs, link is not established. Subsequent cable
plug/unplaug cycle will not correct the issue.
WORk AROUND
There are four approaches to work around this issue:
1. This issue can be prevented by setting bit 15 in MMD device address 1,
register 2, prior to connecting the cable or prior to setting the
Restart Auto-negotiation bit in register 0h. The MMD registers are
accessed via the indirect access registers Dh and Eh, or via the Micrel
EthUtil utility as shown here:
. if using the EthUtil utility (usually with a Micrel KSZ8061
Evaluation Board), type the following commands:
> address 1
> mmd 1
> iw 2 b61a
. Alternatively, write the following registers to write to the
indirect MMD register:
Write register Dh, data 0001h
Write register Eh, data 0002h
Write register Dh, data 4001h
Write register Eh, data B61Ah
2. The issue can be avoided by disabling auto-negotiation in the KSZ8061,
either by the strapping option, or by clearing bit 12 in register 0h.
Care must be taken to ensure that the KSZ8061 and the link partner
will link with the same speed and duplex. Note that the KSZ8061
defaults to full-duplex when auto-negotiation is off, but other
devices may default to half-duplex in the event of failed
auto-negotiation.
3. The issue can be avoided by connecting the cable prior to powering-up
or resetting the KSZ8061, and leaving it plugged in thereafter.
4. If the above measures are not taken and the problem occurs, link can
be recovered by setting the Restart Auto-Negotiation bit in
register 0h, or by resetting or power cycling the device. Reset may
be either hardware reset or software reset (register 0h, bit 15).
PLAN
This errata will not be corrected in the future revision.

There have been reports of oversize UDP packets being sent to the
driver to be transmitted, causing error conditions. The issue is
likely caused by the dst of the SKB switching between 'lo' with
64K MTU and the hardware device with a smaller MTU. Patches are
being proposed by Mahesh Bandewar <maheshb@google.com> to fix the
issue.
In the meantime, add a quick length check in the driver to prevent
the error. The driver uses the TX packet size as index to look up an
array to setup the TX BD. The array is large enough to support all MTU
sizes supported by the driver. The oversize TX packet causes the
driver to index beyond the array and put garbage values into the
TX BD. Add a simple check to prevent this.

When sending multicast messages via blocking socket,
if sending link is congested (tsk->cong_link_cnt is set to 1),
the sending thread will be put into sleeping state. However,
tipc_sk_filter_rcv() is called under socket spin lock but
tipc_wait_for_cond() is not. So, there is no guarantee that
the setting of tsk->cong_link_cnt to 0 in tipc_sk_proto_rcv() in
CPU-1 will be perceived by CPU-0. If that is the case, the sending
thread in CPU-0 after being waken up, will continue to see
tsk->cong_link_cnt as 1 and put the sending thread into sleeping
state again. The sending thread will sleep forever.
CPU-0 | CPU-1
tipc_wait_for_cond() |

// condition_ = !tsk->cong_link_cnt |
while ((rc_ = !(condition_))) { |

devlink: make ethtool compat reliable
This is a follow up to the series which added device flash
updates via devlink. I went with the approach of adding a
new NDO in the end. It seems to end up looking cleaner.
First patch removes the option to build devlink as a module.
Users can still decide to not build it, but the module option
ends up not being worth the maintenance cost.
Next two patches add a NDO which can be used to ask the driver
to return a devlink instance associated with a given netdev,
instead of iterating over devlink ports. Drivers which implement
this NDO must take into account the potential impact on the
visibility of the devlink instance.
With the new NDO in place we can remove NFP ethtool flash update
code.
Fifth patch makes sure we hold a reference to dev while
callbacks are active.
Last but not least the NULL-check of devlink->ops is moved
to instance allocation time.
Last but not least missing checks for devlink->ops are added.
There is currently no driver registering devlink without ops,
so can just fix this in -next.
v2 (Michal): add netdev_to_devlink() in patch 3.
v3 (Florian):
- add missing checks for devlink->ops;
- move locking/holding into devlink_compat_ functions.
v4 (Jiri):
- hold devlink_mutex around callbacks (patch 2);
- require non-NULL ops (patch 6).
